Refer to Fig. 1 and Fig. 3, when reality application display device carries out picture display, a lot of in the case of do not require nothing more than aobvious
Showing device can show a fixing display picture, also requires that display device can be according to actual needs in multiple fixing displays
Switch at any time between picture, in order to meet the needs of this display picture of switching at any time, can be corresponding according to each display picture
Display pattern formed in fiber waveguide 1 correspondence transparent display module 2, and formed multiple transparent display module 2 at least
There is the refractive index refractive index less than fiber waveguide 1 of a transparent display module 2.And, when display device includes a light source 4
Time, it is desirable to when the light sent by this light source 4 incides in fiber waveguide 1, the minimum angle of incidence being correspondingly formed is adjustable；Work as display device
During including multiple light source 4, multiple light sources 4 exist the light that at least two light source 4 sends when inciding in fiber waveguide 1, corresponding
The minimum angle of incidence formed differs, it is possible to make display device show different display patterns.So display device just can be real
Switch at any time between the most each display picture.
Concrete, for convenience, refractive index in multiple transparent display module 2 is less than the saturating of fiber waveguide 1 refractive index
Bright display module 2 is defined as controlled display module, when light is injected in controlled display module by fiber waveguide 1, meet light by
Optically denser medium injects the condition of optically thinner medium, so when display device only includes a light source 4 (such as Fig. 3), and can be by adjusting

Lead 1 when being mapped on controlled display module, the size of the first incidence angle θ 1 of formation, and light is mapped to display by controlled display module
Time in the external environment that device is applied, the size of the second incidence angle θ 2 of formation, thus control light whether can be controlled at this
It is totally reflected on display module, i.e. controls whether display device shows the display pattern that this controlled display module is corresponding.Enter one
Saying of step, when needing to show display pattern corresponding to controlled display module, scalable the first incidence angle θ 1 and the second incidence angle θ
2 cirtical angles of total reflection being larger than correspondence；When need not to show display pattern corresponding to this controlled display module, can
Regulate the first incidence angle θ 1 and/or the second incidence angle θ 2 so that it is in any one angle of incidence more than or equal to corresponding total reflection
Critical angle, thus realize the switching between different display pattern.
Preferably, the folding of the external environment that the refractive index of above-mentioned transparent display module 2 correspondence is applied less than display device
Penetrate rate, so when light by transparent display module 2 directive display device outside time, would not be totally reflected, thus avoid right
The regulation of the second incidence angle θ 2, makes display device switching between difference display picture become more to simplify.
It should be noted that due to the refractive index interfaces of different minimum angle of incidence correspondence zoness of different, when minimum incident
When angle is fixed, when light is by fiber waveguide 1 directive transparent display module 2, it is possible to the refractive index corresponding to transparent display module 2 of outgoing
Scope determines；Therefore, when display device includes a light source 4, the light sent by this light source 4 by regulation incides fiber waveguide
Time in 1, the size of the minimum angle of incidence being correspondingly formed, it becomes possible to control light outgoing from the controlled display module specified, thus
The display picture that display is specified.During additionally, the light sent by light source 4 incides in fiber waveguide 1, the minimum angle of incidence being correspondingly formed
Can be adjusted in several ways, such as: adjust the light source 4 position relative to fiber waveguide 1, or use grating, prism etc.
Change the transmission path of light, thus realize the regulation of minimum angle of incidence；Certainly, these modes it are not limited only to.
And when including multiple light source 4 for display device (such as Fig. 1), multiple light sources 4 can not possess and regulate at any time
The function of lighting angle, when the light that the most each light source 4 sends incides in light guide plate 1, the minimum angle of incidence being correspondingly formed is fixed.?
In the case of Zhong, each light source 4 light sent can be set when inciding in light guide plate 1, each the most not phase of the minimum angle of incidence being correspondingly formed
With, so that the light that each light source 4 sends can be the most real from corresponding appointment controlled display module injection display device
When border application display device carries out picture display, it is possible to by controlling the opening and closing of each light source 4, it is achieved to each display picture
The switching in face.
When needs arrange multiple controlled display module on light guide plate 1, difference can be selected according to actual displayed needs
Material, form the different multiple controlled display module of refractive index, so when reality application display device, it is possible to cut
Change and more show picture.Include as a example by the controlled display module that 5 refractive indexs are different by display device below, for not
